A certain electronics manufacturer is making GPUs for gaming laptops (GPU stands for graphics processing unit). The manufacturer found that the marginal cost CC to produce x GPUs can be found using the equation C=0.03x2−5x+700C=0.03x2-5x+700. If the marginal cost were $509, how many GPUs were produced?
